The Development of Argumentation Skills in the Chemistry Laboratory
One of the key goals of science education is to provide students with the ability to construct arguments – reasoning and thinking critically in a scientific context. Over the years, many studies have been conducted on constructing arguments in science teaching, but only a few of them have dealt with studying argumentation in the science laboratory in general and in the chemistry laboratory in particular. Our research focuses on the process in which students construct arguments in the chemistry laboratory while conducting different types of inquiry experiments. The experiments that were assessed for their argumentation level differed in their level of complexity. It was found that the more complex experiments served as a better platform for developing arguments as well as regarding their relative numbers. Moreover, we identified a number of characteristics during the discourse that serve as a catalyst for raising arguments: asking questions and unexpected results obtained in the experiments.
